The Petrol Ofisi Headquarters Project invitation was opened in 2000 for the renovation of one of the existing building blocks designed for Alarko by Sedad Hakkı Eldem in 1976 and Kreatif Architects undertook the renovation project together with the NSMH Architecture Office.

The basic problem of this project was to rehabilitate the existing building which was designed a quarter century ago by Sedad Hakkı Eldem while keeping its authentic design principles.

The unnecessary additions and arrangements which are made in the past life of the building are cleared away until only the shell and the circulation core remained.Then new functional requirements are added to the naked structure of the building by using light and transportable elements considering that the function of the building may be changed again in the future.
